Prontor 381 (05)
Gauthier Prontor leaf shutter nr.381
This is a guess as there is no name or logo on the shutter and there was written 381 on the box with a pen.
Year of production unknown. Probably somewhere in the 1960s.
As found in its original sparepart box.
This other specimen of the 381 is almost the same EXCEPT for the slot of the shutter time lever which has a different shape (compare with photo 01).
